Only if you browsed daytime /a/. /a/ has(or used to be) generally about the subculture otaku revolving around anime and manga than actual manga and anime itself. People DID discuss anime and manga without shitting over them, back when threads didn't get bumped off the front page in a few seconds.
/a/ has always made fun of anime, but it's always been trolling intended for humor. The problem now is that a lot of people are actually being serious, which isn't funny at all. The board's currently being hijacked by moralfags.
